Scott H. Johnson here. I have written a few pieces for TRAINS.  "Riding the Rails with Riley" Sept 09; "Grief and Joy along the Southern Pacific," July 2013. I grew up along the Southern Railway in West Springfield Va in the 70s and have a fondness for the Southern Crescent and the Piedmont. My N scale layout is based on SE Portland Oregon and Oregon City, OR. Take a look on YouTube "N scale Southern, Chessie trains" and more. Yes, the Southern Crescent rolls through Oregon lol. The avatar is me walking with Graham Claytor just south of the Alexandria VA train station at a 4501 fan trip in the  spring of 77 .
